The entire disclosure of each of the above-noted patent
applications is hereby incorporated by reference herein, and
priority is claimed to each of these three patent applications as
well.
FIELD OF THE INVENTION
[0002] The present invention generally relates to seating devices
and, more particularly, to a portable seating device usable under
multiple seating conditions, such as in conjunction with a
bench-style or hard seating system.
BACKGROUND OF THE INVENTION
[0003] Many spectator event facilities (e.g., stadiums) are
equipped with bench-style or bleacher seating (hereafter
"bleachers") instead of individual seats. Regardless of the various
materials utilized to construct these bleachers, sitting on these
bleachers for extended periods of time can be extremely
uncomfortable. Moreover, the lack of a backrest on these bleachers
may tend to strain and/or aggravate the upper and/or lower back.
Further, while some spectator event facilities are equipped with
individual seats having backrests, these individual seats tend to
be made of metal, hard plastics and/or wood, which have also tended
to contribute to similar user discomfort and/or aggravation. As a
result, many people desiring to attend spectator events have
foregone such attendance due to the discomfort and/or physical
demands associated with sitting on bleachers or hard seats.
Moreover, such user discomfort/aggravation has also been associated
with sitting on bench-style or hard seats associated with picnic
tables, boats, hunting stands (e.g., for deer hunting), and the
like.
[0004] Several attempts have been made to reduce/diminish the
discomfort associated with bench-style and/or hard seating systems,
such as those associated with spectator event seating. In the
simplest attempt, portable cushions have been carried by
individuals to be placed on the hard wooden, metal, or plastic
surface of the seating system. While these cushions may address the
pain of sitting on the hard surface (at least to a limited extent),
they do not address strain on the upper and lower back. In another
attempt, a portable seat combined with a backrest has been utilized
to reduce/alleviate back pain/strain associated with bench-style
and/or hard seating. More particularly, the most common design for
these portable seats is a foldable seat that has both a seat
portion and a backrest that are foldably connected. Although some
of these portable seats have at least somewhat of a solid backrest,
some of these portable seats are equipped with backrests that are
extremely flimsy (e.g., provide a backrest in form, but not in
substance) so that user back pain/strain is still a common
occurrence. While some portable seats have provided limited
substantive relief of back pain/strain associated with sitting in
bleachers or the like, one of the costs associated with the same is
that these portable seats tend to be extremely heavy, which may
make them difficult to transport and/or even unusable for certain
(e.g., elderly and/or physically weak) individuals. Therefore, it
would be desirable to have a portable seat that is relatively light
in weight to enhance its transportability, and further, that may be
adjusted to better accommodate the needs/desires of the particular
user.
SUMMARY OF THE INVENTION
[0005] In view of the foregoing, an objective of the present
invention is to provide an improved portable seating device that
eliminates or at least generally reduces the drawbacks of the
above-mentioned conventional seats. More particularly, an important
objective of the present invention is to provide an improved
portable seating device that is conducive to back mechanics.
Another important objective of the present invention is to provide
an improved portable seating device that is capable of providing
user-specific back support. Yet another objective is to provide a
portable seating device that is easily adjustable and/or
maneuverable. Still another important objective is to provide a
portable seating that is light-weight and/or easy to
transfer/carry. These objectives and additional advantages are
generally realized by the present invention, which generally
relates to a portable seating device, such as, for example, a
portable stadium seat.
[0006] The portable seating device of the present invention
generally includes a seat and a first backrest movably
interconnected with the seat. Herein, "portable," "portability,"
and the like, generally refer to a characteristic of the seating
device of the present invention which enables the same to be freely
moved and/or easily/conveniently transported about by a potential
user. Accordingly, the portable seating device may be said to be
totable. In other words, a potential user may be able to carry a
portable seating device of the invention with him/her "by hand," or
by using an appropriate handle, shoulder strap, backpack, and/or
carry-case. So, for example, "portable" may refer to the seating
device weighing no more than about 10 pounds in one embodiment, no
more than about 7 pounds in another embodiment, and no more than
about 5 pounds in yet another embodiment.
[0007] Further, "movably interconnected," a "movable
interconnection" or the like generally refers to the ability of at
least one of the seat and the first backrest to be relocated
relative to the other. This movably interconnection of the seat and
the first backrest may be characterized as enabling the seating
device to be one or more of folded, collapsed, compacted, packed,
and the like. It may be said that this movable interconnecting
relationship of the seat and the first backrest, at least in one
embodiment, is a "pivotal interconnection," which herein generally
refers to any type of interconnection that allows at least one of
the seat and the first backrest to at least generally undergo a
pivoting or pivotal-like motion relative to the other (e.g., due to
at least one hinge or ball-and-socket type joint), including
without limitation any interconnection that allows the same to move
at least generally about a certain axis (e.g., via flexing or
elastic deformation). Due to the movable interconnection between
the seat and the first backrest, the portable seating device of the
present invention is generally positionable in both a stowed (e.g.,
folded, collapsed, compacted, closed up, packed and/or the like)
position and a deployed (e.g., unfolded, open, usable, employable
and/or the like) position.
[0008] In a first aspect, the present invention is directed to the
first backrest of the portable seating device being selectively
movable at least one of toward and away from a reference plane that
at least generally contains (or is even substantially aligned with)
a seating surface of the seat, at least when the seating device is
in the deployed position. Moreover, this first aspect is also
characterized by a second backrest being both associated with and
selectively movable relative to the first backrest.
[0009] Various refinements exist of the features noted in relation
to this first aspect of the present invention. Further features may
also be incorporated in this first aspect as well. These
refinements and additional features may exist individually or in
any combination. For instance, the second backrest may be
selectively movable at least one of toward and away from the
reference plane at least when the seating device is in the deployed
position. Herein, "selectively movable," when referring to the
first backrest, may generally refer to the first backrest being
positionable in at least first and second positions. So, for
instance, in one embodiment, at least when in the seating device is
in the deployed position, the first backrest is generally disposed
closer to the reference plane than when the first backrest is in
the second position. As an example, when a particular user is
sitting on the portable seating device, the first backrest may
interface with the user's back at a first location when in the
first position; and, by contrast, the first backrest may interface
with the user's back at a second location that is "higher up" the
user's back (relative to the first position) when in the second
position. Moreover, "selectively movable," when referring to the
second backrest, may generally refer to the second backrest being
positionable in at least third and fourth positions relative to the
first backrest. So, for example, when a particular user is sitting
on the portable seating device, the second backrest may interface
with the user's back at one location when in the third position;
and by contrast, the second backrest may interface with the user's
back at another location that is "higher up" the user's back
(relative to the third position) when in the fourth position.
Indeed, the second backrest associated with this first aspect may
be typified as an adjustable lumbar pad or cushion in at least one
embodiment. In one embodiment that has a pivotal interconnection
between the seat and the first backrest, it may be said that at
least one of the first and second backrests is selectively movable
at least one of toward and away from the pivotal interconnection
that movably interconnects the first backrest and the seat (at
least when the portable seating device is in the deployed
position). Regarding this movement and/or positioning of one or
both the first and second backrests, it is preferred that the same
can be accomplished by hand. Herein, "by hand" generally means
without the use of a machine or tool.
[0010] Still referring to the first aspect of the present
invention, the portable seating device may have a cover
substantially disposed about both the first and second backrests.
This cover may be characterized as housing a majority (and, in one
embodiment, the substantial entirety) of both of the first and
second backrests. At least in one embodiment, this cover may be
said to at least assist in maintaining a position of the second
backrest relative to the first backrest. This position maintenance
function of the cover may be due to the cover being designed to at
least generally bias at least one of the first and second backrests
toward the other. This biasing at least generally enables a
frictional interface of sorts to exist between the first and second
backrests that enables positional maintenance of the second
backrest relative to the first. Accordingly, in one embodiment, to
adjust a positioning of the second backrest, a user would simply
loosen and/or remove at least a portion of the cover to expose at
least a portion of one or both the first and second backrests. The
second backrest can be positioned at a desired location relative to
the first backrest, and the cover can be put back on and/or
tightened to hold the desired position of the second backrest
relative to the first. In another embodiment, the cover may be at
least generally stretchable, so that the user may simply reach
under the cover to move the second backrest to the desired location
relative to the first.
[0011] The first backrest associated with the portable seating
device of the first aspect may, at least in one embodiment, include
a frame. This frame may be pivotally interconnected with the seat,
and may include any appropriate frame material. However, due to
desired the portable nature of the seating device, lighter frame
materials may be preferable over heavier materials. The first
backrest may be said to be movably interconnected with the frame.
Accordingly, the first backrest may be selectively movable at least
generally along (and relative to) the frame. So, in embodiments
that may be characterized as having a first backrest that can be
positioned in at least first and second positions, these first and
second positions may correspond with respective first and second
locations along the frame.
[0012] Along similar lines, one embodiment of the first backrest of
the portable seating device of the first aspect may include at
least one aperture configured so that at least one fastener (e.g.,
appropriate screws, bolts/nuts, pins and the like) associated with
the second backrest is extendable through the aperture(s).
Preferably, this fastener associated with the second backrest
enables a person (e.g., a user) to adjust and/or position the
second backrest relative to the first backrest by hand. The
aperture(s) of the first backrest may be any appropriate
configuration. For example, the aperture(s) may be at least one
elongate channel or a plurality of apertures disposed in a
substantially linear configuration. In an embodiment having the
above-described channel(s), the second backrest may be
characterized as being movable along these channel(s) relative to
the first backrest.
[0013] A further feature that may be indicative of the portable
seating device of the first aspect is that the first backrest (and
thus, the second backrest associated therewith) may be detached
from a remainder of the seating device and, therefore, capable of
being utilized without the remainder of the seating device. In
other words, the first backrest may be removed from the rest of the
seating device and used to supplement/enhance the comfort and/or
support provided by a separate seating system that is already
equipped with a back, such as a chair or any type of transport seat
(e.g., car seat, airplane seat, bus seat, train seat, boat seat).
Preferably, this detachment of the first backrest from the
remainder of the seat is accomplishable by hand. Moreover, the
first backrest preferably is equipped with a mechanism that enables
the same to be releasably interconnected with the separate seating
system by hand. Examples of appropriate manners for associating the
first backrest of the seating device with the separate seating
system may include hooks, straps, Velcro.RTM. and the like.
[0014] Yet still referring to the first aspect of the present
invention, the portable seating device may include a base that is
interfacable with a support structure (e.g., a bench, bleacher,
chair, the ground, or the like) on which the seating device is to
be supported. Moreover, the seating device may include a mechanism
for rotatably interconnecting the seat with the base. Accordingly,
the seat of such an embodiment may be characterized as being
rotatable or spinnable (at least to some extent) relative to the
base. Herein, "rotatably interconnecting" or the like generally
refers to an associative relationship that enables the seat to
rotate (e.g., turn about an axis) relative to the base. While any
mechanism capable of enabling a seat to rotate relative to a base
may be appropriate for inclusion in this first aspect, at least one
example of such an appropriate mechanism is disclosed in relation
to a second aspect of the present invention described below.
[0015] In still another embodiment associated with this first
aspect, the portable seating device may include a stand. This stand
may be characterized as having a first end that is detachably
interconnectable with the base. Moreover, the stand may also have a
second end, generally opposite from the first end that may be said
to be both spaced from the base and interfacable with a supporting
surface (e.g., a floor or the ground) on which the seating device
is to be supported when the first end is detachably interconnected
with the base. Herein, "detachably interconnectable" generally
refers to a capability of the stand to be coupled (e.g., attached
or joined) with and/or decoupled (e.g., detached or separated) from
the seat as desired over multiple occasions. Preferably, this
detachable interconnection can be accomplished by hand (e.g.,
without the use of tools/machines). While any design/configuration
of a stand that is detachably interconnectable with a seat of a
seating device may be appropriate for inclusion in this first
aspect, a particular example of at least one appropriate stand is
disclosed in relation to a third aspect of the present invention
described below.
[0016] Turning now to a second aspect of the present invention, the
portable seating device of the second aspect generally includes a
base, a seat that is rotatable relative to the base, and a first
backrest. The seat associated with this second aspect generally has
a seating surface and a bottom disposed substantially opposite of
the seating surface. The bottom of this seat may be contained
within or defined by an outer perimeter of the same. In addition,
the portable seating device of the second aspect includes a swivel
disposed between the seat and the base. More specifically, the
swivel associated with this second aspect generally includes a
plurality of bearings. Further, each of at least first and second
bearings (of the previously mentioned plurality of bearings) is
generally spaced from the outer perimeter of the bottom of the seat
by no more than about 4 inches.
[0017] Various refinements exist of the features noted in relation
to this second aspect of the present invention. Further features
may also be incorporated in this second aspect as well. These
refinements and additional features may exist individually or in
any combination. For example, the swivel may include a post. In one
embodiment, the post may extend into at least one of the seat and
the base. The post associated with some embodiments of this second
aspect may be characterized as being substantially annularly
disposed about a rotational axis of the swivel. Moreover, in at
least one embodiment, the swivel's plurality of bearings may be
symmetrically disposed about the axial post or at least the
rotational axis (e.g., in embodiments devoid of an post). Referring
to the bearings associated with the second aspect of the present
invention, at least one of the bearings may be characterizable as
being in direct contact with both the base and the seat. In other
words, the base and the seat may be oriented such that they
"sandwich" the bearings between the same.
[0018] The first and second bearings associated with this second
aspect are generally positioned so that they may provide a benefit
of enabling the seat to easily rotate (relative to the base), even
under heavy loads or when weight on the seating surface is unevenly
positioned. Moreover, the positioning of the first and second
bearings may at least generally promote a maintenance of a spacing
between the base and the seat (e.g., under conditions of uneven
weight disbursement on the seat). Still referring to these
bearings, each of first and second bearings (as well as other
bearings) may be spaced from the outer perimeter of the bottom of
the seat by no more than about 3 inches in one embodiment, no more
than about 2 inches in another embodiment, and even no more than
about 1 inch in yet another embodiment. In another light, each of
first and second bearings may be described as being spaced from the
rotational axis of the swivel by at least about 3 inches in one
embodiment, at least 4 inches in another embodiment, at least about
5 inches in another embodiment, and at least about 6 inches in
still another embodiment. Still other characterizations may be
appropriate for describing the peripheral positioning of at least
the first and second bearings.
[0019] Still referring to the case of the second aspect of the
present invention, the portable seating device may be equipped with
a rotational lock. This rotational lock may be said to at least
generally selectively prevent and allow rotation of the seat
relative to the base. For example, in a "locked" position, the
rotational lock may at least generally couple the base and the seat
in such a manner that the seat cannot rotate relative to the base.
Conversely, in an "unlocked" position, the rotational lock may be
prevented from substantially inhibiting rotation of the seat
relative to the base (and/or vice versa). While various designs and
arrangements of rotational locks may be appropriately employed with
regard to this second aspect of the present invention, a particular
example of such an appropriate rotational lock is a locking pin or
the like.
[0020] Yet still referring to the second aspect of the present
invention, the base of the portable seating device may be said to
be at least generally interfacable with a separate and distinct
seating assembly (e.g., a bench, bleacher, chair, or the like) on
which the seating device is to be supported. The portable seating
device of this second aspect may include yet other refinements. For
example, in one embodiment, the first backrest may be selectively
movable at least one of toward and away from the seating surface
(at least when the seating device is in the deployed position). The
first backrest may even be characterized as being rotationally
dependent upon on the seat relative to the base. That is, if the
seat is rotated, the first backrest may be structurally required to
rotate in chorus with the seat. In another embodiment, the portable
seating device may include a stand that has a first end that is
detachably interconnectable with the base. Moreover, the stand may
also have a second end, generally opposite from the first end that
may be said to be both spaced from the base and interfacable with a
supporting surface (e.g., a floor or the ground) on which the
seating device is to be supported when the first end is detachably
interconnected with the base. Moreover, the stand may be rotatably
immobile relative to and when detachably interconnected with the
base. In other words, when the stand engages with the base, the
stand may be prevented from rotating relative to the base. While
any design/configuration of a stand that is detachably
interconnectable with a base of a seating device may be appropriate
for inclusion in this second aspect, a particular example of at
least one appropriate stand is disclosed in relation to the third
aspect of the present invention described below.
[0021] The above-mentioned third aspect of the present invention is
directed to a portable seating device having a stand that includes
first and second supports that are pivotally interconnected with
one another, and first and second ends associated with each of the
first and second supports. The first end of each of these first and
second supports is detachably interconnectable with the seat.
Moreover, the second end of each of the first and second supports
is both spaced from the seat and interfacable with a supporting
surface (e.g., the ground or a floor) on which the seating device
is to be supported when the first end of each of the first and
second supports is detachably interconnected with the seat.
[0022] Various refinements exist of the features noted in relation
to this third aspect of the present invention. Further features may
also be incorporated in this third aspect as well. These
refinements and additional features may exist individually or in
any combination. The stand may be detachably interconnectable with
the seat. For example, the seating device preferably includes a
mechanism for attaching and/or detaching the stand and the seat by
hand (e.g., without the use of tools/machines). In one embodiment,
the seating device may be designed so that the stand can simply be
"snapped" into engagement with the seat. In other words, the
seating device may be configured so that a press fit joint of sorts
can be utilized to detachably interconnect the stand and the seat.
A benefit of using such a press fit design is that the stand can
generally be both attached to and detached from the seat by hand.
Moreover, one or more mechanical fasteners may be utilized to
detachably interconnect the stand and the seat (e.g., a locking
pin, with or without the noted press fit connection). In one
embodiment, the mechanical fastener(s) may extend through the stand
and at least a portion of the seat. The seating device may be
characterized as being equipped with a mechanism to enable the
stand and a bottom of the seat to be detachably interconnected. At
least in one embodiment, this mechanism (e.g., a receiving portion
of the above-described press fit joint) is generally positioned (or
positionable) within an outer perimeter of the bottom of the seat.
That is, however the seat and the stand are detachably
interconnected with one another, the entirety of the mechanism
enabling the same may be located under (or even substantially
concealed by) the seat.
[0023] Still referring to the stand associated with the third
aspect of the present invention, the stand may be said to be
collapsible. That is, the stand (at least in one embodiment) may be
capable of being "folded" or the like, for example, to enhance ease
of storing and/or transporting the same. Another embodiment may be
characterized by each of the first and second supports having first
and second legs. Stated another way, the stand may have at least
four legs.
[0024] Yet still referring to the third aspect of the present
invention, the portable seating device may include a base and a
mechanism for rotatably interconnecting a seating portion of the
seat with the base. Accordingly, the seating portion of such an
embodiment may be characterized as being rotatable or spinnable (at
least to some extent) relative to the base. Moreover, the stand is
generally detachably interconnectable with the base of the seat in
such embodiments. In another embodiment, the first backrest of the
seating device of the third aspect may be selectively movable at
least one of toward and away from the seating surface (at least
when the seating device is in the deployed position).
[0025] The stand utilized by the third aspect may have at least one
of the first and second supports be of a telescoping configuration
(e.g., so that the first and/or second support may be extended or
retracted to a desired length). This would allow the length of the
first support, the second support, or both to be adjusted. One
instance where this feature may be particularly desirable is where
the portable seating device is being used on uneven ground. This
may then be used to maintain the seat in at least somewhat of a
horizontal position.
[0026] A fourth aspect of the present invention is directed to a
portable seating device. This portable seating device includes a
seat and frame, where the frame in turn includes first and second
frame sections. The first frame section is mounted on the seat. The
second frame section is movably interconnected with the first frame
section so as to be movable between stowed/collapsed and
deployed/expanded positions. The first and second frame sections
further are disposed in a telescoping or telescoping-like fashion
so that the length of the frame may be increased or decreased at
least when the second frame section is in the deployed position. In
this regard, a first backrest is interconnected with the second
frame section. This first backrest is selectively movable by the
telescoping action available between the first and second frame
sections to change the vertical position of the first backrest when
in its deployed position. This may then be used to adjust the
position where the first backrest engages the back of an individual
that is using the portable seating device.
[0027] Various refinements exist of the features noted in relation
to this fourth aspect of the present invention. Further features
may also be incorporated in this fourth aspect as well. These
refinements and additional features may exist individually or in
any combination. The first frame section may remain in a fixed
position relative to the seat. The first and second frame sections
may be disposed at least generally perpendicular to the seat in
this instance or at any other desired angle. The second frame
section may be disposed at least generally parallel with the seat
when in its stowed position. The second frame section may be
pivotally interconnected with the first frame section to allow for
movement between the stowed and deployed positions.
[0028] The portable seating device of the fourth aspect may further
include a base. The base may be disposed directly on an appropriate
supporting surface (e.g., planar, continuous). In one embodiment,
the lower surface of the seat and the upper surface of the base are
separated by a space of no more than about 1/4 inch. This base may
include an upper base surface that at least generally projects away
from this supporting surface when the base is disposed thereon, and
further that is disposed no more than about 2.5 inches from the
supporting surface in one embodiment. Therefore, the base has what
many characterized as a low profile when disposed on the supporting
surface. Furthermore, the base may be supported on the supporting
surface so that it has a constant vertical position relative to the
supporting surface. Stated another way, the base preferably does
not "rock" when disposed on the supporting surface, regardless of
where the load is applied on the base. This may be realized by
having the portions of the base that interface with the supporting
surface collectively define a perimeter having an area of at least
about 144 in..sup.2 in one embodiment, and at least about 289
in..sup.2 in another embodiment. In one embodiment, the base is at
least generally the same size as the seat (their respective outer
perimeters).
[0029] The above-noted base that may be associated with the fourth
aspect may include a planar bottom surface that interfaces with the
supporting surface such that the base is stable when disposed on
the supporting surface. The base could further include a bottom
surface that is not planar, but where the lowest portions of the
bottom surface are collectively disposed within a common reference
plane. What may be characterized as low profile rails, feet, legs
or the like could extend down from the base to engage the
supporting surface. These rails, feet, legs or the like could be
integrally formed with the base or could be detachably
interconnected therewith.
[0030] In addition to the foregoing, any of the various features
discussed above in relation to any of the first, second, and third
aspects, as well as those to be discussed below in relation to the
fifth aspect, may be used by this fourth aspect, individually or in
any combination.
[0031] A fifth aspect of the present invention is directed to a
portable seating device. This portable seating device includes a
base. The base may be disposed directly on an appropriate
supporting surface (e.g., planar, continuous). Those portions of
the base that interface with the supporting surface collectively
define a perimeter having an area of at least about 144 in..sup.2,
and at least about 289 in..sup.2 in another embodiment. A seat is
movably interconnected with this base (e.g., rotational motion,
swiveling motion), and a frame is mounted on this movable seat. At
least a portion of this frame is movable between stowed and
deployed positions. A first backrest is interconnected with this
movable portion of the frame so as to also be movable between
stowed and deployable positions as well.
[0032] Various refinements exist of the features noted in relation
to this fifth aspect of the present invention. Further features may
also be incorporated in this fifth aspect as well. These
refinements and additional features may exist individually or in
any combination. In one embodiment, the center of the "support"
region or area coincides with the center of the area defined by the
perimeter of the seat. The base may be characterized as having an
upper base surface. In one embodiment this upper base surface at
least generally projects away from this supporting surface when the
base is disposed thereon, and further is disposed no more than
about 2.5 inches from the supporting surface. Therefore, the base
has what may characterized as a low profile when disposed on the
supporting surface. In one embodiment, a lower surface of the seat
and an upper surface of the base are separated by a space of no
more than about 1/4 inch. Furthermore, the base may be supported on
the supporting surface so that it has a constant vertical position
relative to the supporting surface, regardless of where the load is
applied on the base. Stated another way, the base preferably does
not "rock" when disposed on the supporting surface.
[0033] The base of the subject fifth aspect may include a planar
bottom surface that interfaces with the supporting surface such
that the base is stable when disposed on the supporting surface.
The base could further include a bottom surface that is not planar,
but where the lowest portions of the bottom surface are disposed
within a common reference plane. Low profile rails, feet, legs or
the like could extend down from the base to engage the supporting
surface. These feet, legs or the like could be integrally formed
with the base or could be detachably interconnected therewith. In
addition to the foregoing, any of the various features discussed
above in relation to any of the first, second, third, and fourth
aspects may be used by this fifth aspect, individually or in any
combination.
[0034] A sixth aspect of the present invention is directed to a
portable seating device. This portable seating device includes a
seat and frame. At least a portion of the frame is collapsible to
allow the frame to be moved between a stowed position and at least
one deployed position. A first backrest is mounted on a collapsible
portion of the frame. This first backrest is selectively movable
relative to the seat to change the vertical position of the first
backrest when the frame is in a deployed position. This may then be
used to adjust the position where the first backrest engages the
back of an individual that is using the portable seating device.
Any of the various features discussed above in relation to any of
the first, second, third, fourth, and fifth aspects may be used by
this sixth aspect, individually or in any combination.
[0035] The various features discussed above in relation to any of
the aspects of the present invention may be incorporated into any
of the other aspects of the present invention as well, and in the
manner noted herein. Moreover, various other refinements may be
appropriately included in any of the aspects described above. For
instance, the seat and base may be of any appropriate size, shape,
configuration, and/or construction. The portable seating device
also may be equipped with a beverage holder that is generally
interconnected (or interconnectable) with the seating device (e.g.,
the seat). In one embodiment, this beverage holder may even be
characterized as being retractable, so that it is at least
generally concealed by the seat when in an inactivated condition
and at least generally exposed for use (e.g., along side the seat)
when in an active condition. Further, the portable stadium seat may
include one or more storage compartments (e.g., associated with at
least one of the backrest and the seat). So, for example, a
backside of the first backrest may be equipped with a pocket or
compartment. Moreover, the seat may have a storage compartment, at
least a portion of which may even be disposed between the seating
surface and the bottom of the seat so that the storage compartment
may be at least partially disposed within the seat. As still
another refinement, the portable seating device may be equipped
with one or more apparatuses to at least generally assist in
enabling a user to carry the portable seating device. Examples of
appropriate carrying apparatuses may include things such as
handles, shoulder straps, backpacks, carry-cases, and the like. As
still yet another refinement, the portable seating device may
include one or more mechanisms (e.g., hooks, straps, and the like)
for releasably interconnecting the portable seating device with
another separate and distinct seating system such as a bleacher
seat, a folding chair, a chair, a picnic table, a boat seat, a
kayak seat, a hunting stand, and others.
[0036] A seventh aspect of the present invention is directed to a
portable seating device having a seat, a base, and a first
backrest, where the seat is rotatably interconnected with the base,
and where the first backrest is at least interconnectable with the
seat. The seat includes an upper seat section and a lower seat
section, where the upper seat section is disposable over the lower
seat section. At least one of the upper seat section and the lower
seat section includes at least one storage compartment that is
accessible by moving the upper seat section at least generally away
from the lower seat section in any appropriate manner.
[0037] Various refinements exist of the features noted in relation
to the seventh aspect of the present invention. Further features
may also be incorporated in the seventh aspect as well. These
refinements and additional features may exist individually or in
any combination. Any way of allowing the upper seat section to move
at least generally away from the lower seat section may be
utilized. For instance, the upper seat section and the lower seat
section may be interconnected by a hinge of any appropriate size,
shape, configuration, and/or type. In this case, the upper seat
section may be characterized as being pivotally interconnected with
the lower seat section. It may also be appropriate for the upper
seat section to be detachably interconnected with the lower seat
section such that the upper seat section may be entirely
removed/disengaged from the lower seat section to access one or
more storage compartments associated with the seat.
[0038] One or more storage compartments may be integrated with the
seat in any appropriate manner in the case of the seventh aspect.
One embodiment has one or more storage compartments existing on a
lower surface of the upper seat section--the lower surface of the
upper seat section facing the lower seat section when the upper
seat section is disposed on/over the lower seat section. Another
embodiment has one or more storage compartments existing on an
upper surface of the lower seat section--the upper surface of the
lower seat section facing the upper seat section when the upper
seat section is disposed on/over the lower seat section. Yet
another embodiment has one or more storage compartments existing on
the noted lower surface of the upper seat section and has one or
more storage compartments existing on the noted upper surface of
the lower seat section. A storage compartment of the upper seat
section may cooperate with a storage compartment of the lower seat
section to collectively define a storage volume/space of a desired
size. One or more autonomous storage compartments may be provided
for the upper seat section, for the lower seat section, or both. An
appropriate cover may be provided for any of the noted storage
compartments. Such a cover may selectively close/provide access to
one or more storage compartments in any appropriate manner (e.g.,
by an appropriate detachable interconnection; by being
removable).
[0039] The following features may be used by the portable seating
device of the seventh aspect, individually or in any appropriate
combination: 1) the first backrest may be movable between a
stowed/collapsed position and a deployed position, where the first
backrest faces the upper seat section in the stowed position; 2) a
vertical position of the first backrest may be adjustable in any
appropriate manner, including when the first backrest is in the
above-noted deployed position; 3) a second backrest may be disposed
within a perimeter of the first backrest so as to be disposed
between the first backrest and a user that is sitting on the seat,
and this second backrest may be selectively movable relative to the
first backrest (including in a vertical dimension when the first
backrest is in the above-noted deployed position) and without
having to move the first backrest; 4) the first backrest may be
completely detached from the seat so as to be usable independently
of the seat; and 5) a stand may be detachably interconnected with
the seat, where this stand supports the seat above an appropriate
supporting surface (e.g., the ground) and in spaced relation to
this supporting surface when interconnected with the seat such that
the portable seating device is then configured for a lawn chair
like application. The various features discussed above in relation
to the first through the sixth aspect may also be used by this
seventh aspect, individually or in any combination.

DETAILED DESCRIPTION
[0062] The present invention will now be described in relation to
the accompanying drawings that at least assist in illustrating its
various pertinent features. FIGS. 1-2 illustrate one embodiment of
a portable seating device 100. Primary components of the portable
seating device 100 are a seat 104 that is movably interconnected
with a base 152, a stand 172 that is preferably detachably
interconnected with the base 152 in any appropriate manner to
dispose the seat 104 a desired distance above the subject
supporting surface (e.g., a floor, the ground), a collapsible frame
120, and a backrest assembly 127 that is movably interconnected
with the frame 120. The ability to detach the stand 172 from the
base 152, along with the ability to collapse the frame 120 relative
to the seat 104, contribute to the portability/transportability of
the portable seating device 100. Various comfort-related features
are included in the portable seating device 100. For instance, the
seat 104 rotates or swivels relative to the base 152. Certain
adjustment features are also provided in relation to the backrest
assembly 127 to enhance an individual's comfort when using the
portable seating device 100. The portable seating device 100 is
also versatile in that it may reconfigured for the desired
application (e.g., it is usable with the stand 172 or without the
stand 172, for instance on a bleacher seat or the like). These and
other desirable features of the portable seating device 100 will
now be described in more detail.
[0063] Reference will now be made primarily to FIGS. 1-6 for a
discussion of the configuration of the seat 104, frame 120, and
backrest assembly 127. The seat 104 includes a cushion or upper
seat section 108 having an upper seat surface 106a. The cushion 108
may be formed from any appropriate material and may be contoured in
any appropriate configuration to enhance the comfort of an
individual that is using the portable seating device 100.
Preferably the cushion 108 is of a reduced weight so as to not
adversely affect the portability of the portable seating device 100
to an undesired degree.
[0064] Another component of the seat 104 is a platform, bottom, or
lower seat section 112 that supports the cushion 108. The cushion
108 may be mounted on the platform 112 in any appropriate manner,
including both a fixed and detachable mounting. In any case,
preferably the relative movement between the cushion 108 and the
platform 112 is limited to a compression of the cushion 108 by the
weight of an individual using the portable seating device 100. That
is, the cushion 108 and platform 112 in effect function as a single
unit. The platform 112 may be formed from any appropriate material
and may be of any appropriate configuration. In the illustrated
embodiment the platform 112 is a solid plate-like structure.
Preferably the platform 112 is of a reduced weight so as to not
adversely affect the portability of the portable seating device 100
to an undesired degree.
[0065] The frame 120 provides an interface or interconnection
between the seat 104 and the backrest assembly 127. The frame 120
includes one frame section in the form of an upper tube 122 (e.g.,
U-shaped in the illustrated embodiment) that is movably
interconnected with another frame section in the form of a pair of
lower tubes 124 so as to be able to vary the position of the upper
tube 122 relative to the pair of lower tubes 124. The lower tubes
124 are fixed to the seat 104 in a stationary position. Therefore,
movement of the upper tube 122 relative to the lower tubes 124 and
seat 104 varies the location at which the backrest assembly 127
supports the back of an individual using the portable seating
device 100. The frame 120 is also collapsible as will be discussed
in more detail below to allow movement between a stowed or
collapsed position and at least one deployed or expanded position.
Other configurations of the frame 120 that provide this
functionality may be utilized. The frame 120 also may be formed
from any appropriate material. However, preferably the frame 120 is
of a reduced weight so as to not adversely affect the portability
of the portable seating device 100 to an undesired degree.
[0066] The upper tube 122 of the frame 120 includes a plurality of
adjustment holes 123 on each of its two legs. Any appropriate
number of adjustment holes 123 may be utilized. There is a
telescoping relation between the upper tube 122 and the pair of
lower tubes 124. In the illustrated embodiment, each lower tube 124
extends within the interior of the upper tube 122 and includes a
compressible adjustment pin 125. Changing the vertical position of
the upper tube 122 relative to the lower tubes 124 thereby simply
requires compression of each adjustment pin 125 such that the upper
tube 122 may be advanced relative to the pair of lower tubes 124 so
as to dispose each adjustment pin 125 with a particular adjustment
hole 123. The adjustment pins 125 may then be released to lock the
position of the upper tube 122 relative to the pair of lower tubes
124.
[0067] Each lower tube 124 further includes a pivotal connection
132 that separates the lower tube 124 into a first section 124a and
a second section 124b, respectively (e.g., FIG. 3-4). The first
section 124a of each lower tube 124 is appropriately mounted on or
anchored to the platform 112 of the seat 104. A second section 124b
of each lower tube 124 interfaces with a corresponding leg of the
upper tube 122. Each pivotal connection 132 includes a frame 133
(e.g., an at least generally U-shaped sleeve), a pivot pin 134 that
extends through aligned holes in the frame 133, the first section
124a, and its corresponding second section 124b, and a removable
locking pin 135 that extends through holes in the frame 133, the
first section 124a and the corresponding second section 124b when
properly aligned.
[0068] The backrest assembly 127 is movably interconnected with the
seat 104 to support the back of an individual using the portable
seating device 100 at a desired location. Various features are
included in this backrest assembly 127 to enhance user comfort. The
backrest assembly 127 includes a first backrest 128. Brackets or
clamps 126 are used to mount the first backrest 128 on the upper
tube 122 of the frame 120 in the illustrated embodiment. Any
appropriate way of fixing the position of the first backrest 128
relative to the upper tube 122 of the frame 120 may be utilized. As
such, the vertical position of the first backrest 128 is adjustable
by movement of the upper tube 122 of the frame 120 relative to the
pair of lower tubes 124 of the frame 120. The first backrest 128
may be formed from any appropriate material and may be contoured in
any appropriate configuration to enhance the comfort of an
individual that is using the portable seating device 100.
Preferably the first backrest 128 is of a reduced weight so as to
not adversely affect the portability of the portable seating device
100 to an undesired degree.
[0069] The backrest assembly 127 further includes a second backrest
130 that is disposed against the surface of the first backrest 128
that faces the back of an individual that is using the portable
seating device 100 (e.g., FIGS. 5-6). The position of the second
backrest 130 may be adjusted relative to the position of the first
backrest 128. One characterization of the second backrest 130 is
that the same is a lumbar support or the like. In any case, the
second backrest 130 may be formed from any appropriate material and
may be contoured in any appropriate configuration to enhance the
comfort of an individual that is using the portable seating device
100. Preferably the second backrest 130 is of a reduced weight so
as to not adversely affect the portability of the portable seating
device 100 to an undesired degree. More than one second backrest
130 could be utilized as well (not shown).
[0070] The cover 136 is disposed over both the first backrest 128
and the second backrest 130 to retain the second backrest 130 in a
desired position relative to the first backrest 128. In one
embodiment the cover 136 provides the sole mechanism for retaining
the second backrest 130 in the desired position relative to the
first backrest 128. However, the cover 136 may be used in
combination with another mechanism of any appropriate type to
provide this function (e.g., male/female Velcro.RTM. strips on the
backrests 128, 130). The cover 136 may serve other appropriate
functions, such as enhancing the aesthetics of the portable seating
device 100 by including desired graphics or the like. Enhancement
of the ability of the cover 136 to retain the second backrest 130
in the desired position relative to the first backrest 128 may be
realized by forming the cover 136 from elastic or stretchable
materials or the like. In this case, the position of the second
backrest 130 relative to the first backrest 128 can be easily
adjusted in any appropriate manner with the cover 138 partially or
completely installed (e.g., grasping the second backrest 130
through the cover; disposing a hand under the cover 136 to directly
engage the second backrest 130).
[0071] Another way to provide for adjustment of the position of the
second backrest 130 relative to the first backrest 128 is
illustrated in FIG. 7-8. A "single prime" designation is used to
identify components that differ in some respect from the embodiment
of FIGS. 1-6. The backrest assembly 127' includes a first backrest
128' having an at least generally elongate channel or slot 140. Any
number of slots 140 could be utilized. The vertical position of the
second backrest 130 is adjustable relative to the first backrest
128' in the illustrated embodiment by embedding a stud 144 or the
like in the second backrest 130 and directing this stud 144 through
the slot 140 from the front side of the first backrest 128'. The
stud 144 may be moved along the slot 140 to dispose the second
backrest 130 in a desired vertical position relative to the first
backrest 128'. Once in the desired vertical position, a nut 148
that is mounted on the stud 144 on the back side of the first
backrest 128' may be rotated an appropriate amount to pull the
second backrest 130 against the first backrest 128' and thereby
retain the second backrest 130 in a fixed position relative to the
first backrest 128'. The cover 136 could of course thereafter be
positioned over the backrest assembly 127'. Another option would be
for each stud 144 to also be threadably engaged with the first
backrest 128'. This would allow not only the "up and down" position
of the second backrest 130 to be adjusted relative to the first
backrest 128' in the above-noted manner, but the distance that the
second backrest 130 is disposed from the first backrest 128' along
a line that is at least generally perpendicular to the first
backrest 128' as well. That is, the amount that the second backrest
130 protrudes from the first backrest 128' may be adjusted. In this
regard, at least two slots 140, as well as at least one stud 144
per slot 140 (i.e., more that one stud 144 could be provided per
slot 140), may be utilized to interconnect the second backrest 130
with the first backrest 128'. This would provide enhanced
stability, particularly for the case where the position of the
second backrest 130 is adjusted to provide a space between the
second backrest 130 and the first backrest 128'.
[0072] FIGS. 5-6 and FIGS. 7-8 illustrate two ways in which the
position of the second backrest 130 may be adjusted relative to the
first backrest 128. Other ways may be appropriate for providing
this type of adjustment.
[0073] Based upon the foregoing, the backrest assembly 127 provides
a number of desirable functions in relation to the portable seating
device 100. One is that the vertical position of the first backrest
128 may be adjusted so that the first backrest 128 engages a
desired location on the back of the individual using the portable
seating device 100. Another characterization of this feature is
that the vertical position of the first backrest 128 is adjustable
relative to the seat 104. Compare the position of the first
backrest 128 in FIGS. 3 and 4, where the arrows in FIG. 4
illustrate the direction in which the upper tube 122 and
accompanying first backrest 128 were moved simultaneously from the
position illustrated in FIG. 3 to adjust the vertical position of
the first backrest 128 relative to the seat 104 to that illustrated
in FIG. 4.
[0074] Another desirable function provided by the backrest assembly
127 is its ability to adjust the position of the second backrest
130 relative to the first backrest 128. Compare the position of the
second backrest 130 in FIGS. 5-6, where the arrows in FIG. 6
illustrate the direction in which the second backrest 130 was moved
from the position illustrated in FIG. 5 to that illustrated in FIG.
6. The second backrest 130 may be moved in any appropriate manner
relative to the first backrest 128, and is preferably at least
generally retainable in the adjusted position. Moreover, the second
backrest 130 may be of any desirable shaped. Multiple second
backrests 130 also may be utilized as noted (not shown).
[0075] Yet another desirable function provided by the way in which
the backrest assembly 127 is integrated with the portable seating
device 100 is its ability to collapse to reduce the space consumed
by the portable seating device 100 for storage and/or transport.
This is illustrated in FIGS. 9-10. FIG. 9 illustrates a collapsed
or stowed position for the backrest assembly 127. Here the first
backrest 128 has been moved so as to contact the cushion 104 of the
seat 104 or so as to be at least generally horizontally disposed.
Another characterization of this position is that it disposes the
upper portion of the frame 120 in at least generally parallel
relation with the seat 104. In the illustrated embodiment, the
lower section 124a of each lower tube 124 remains in a stationary
position, while upper section 124b of each lower tube 124, along
with the upper tube 122 and backrest assembly 127, pivots to an at
least generally horizontal position or one where the upper section
124b of each lower 124 is disposed at least generally parallel with
the seat 104.
[0076] FIG. 10 illustrates what may be characterized as a deployed
or expanded position for the frame 120 and interconnected backrest
assembly 127, where the upper portion of the frame 120 and the
backrest assembly 127 have been moved at least generally away from
the seat 104 in the direction of arrow. This disposes both the
frame 120 and the first backrest 128 in at least somewhat of a
vertical position. The frame 120 could be disposed at any desired
angle in the deployed position. More than one deployed position
could be available by appropriately configuring the frame 20. That
is, the frame 120 and first backrest 128 could be disposed in what
may be characterized as multiple angular positions relative to the
seat 104. How the frame 120 and backrest assembly 127 are able to
move between the two positions illustrated in FIGS. 9 and 10 is
discussed above in sufficient detail and will not be repeated.
[0077] Support for the above-discussed seat 104 is provided by the
base 152. The base 152 thereby must have sufficient structural
strength so as to support an individual when using the portable
seating device 100. However, the weight of the base 152 is
preferably kept to at least somewhat of a minimum so as to not
adversely affect the portability of the portable seating device 100
to an undesired degree.
[0078] Broadly speaking, the seat 104 is movably interconnected
with the base 152. In the illustrated embodiment this is provided
by disposing what may be characterized as a swivel 154 between the
movable seat 104 and the stationary base 152 and which is
illustrated in FIGS. 11-12. This swivel 154 allows the seat 104 to
rotate or swivel relative to the stationary base 152 (e.g., in the
direction indicated by the arrow in FIG. 2). Details regarding this
swivel 154 are illustrated in FIGS. 11 and 12 as noted. Referring
first to FIG. 11, the surface 153a of the base 152 that projects
toward and/or interfaces with the seat 104 (an upper base surface
153a) includes an aperture 156 that extends all the way through the
base 152. This aperture 156 in effect locates the axis about which
the seat 104 will rotate or swivel relative to the base 152.
[0079] Referring now to FIG. 12, the surface of the platform 112 of
the seat 104 that projects toward or interfaces with the base 152
includes a short post 164 or the like. This post 164 is part of the
swivel 154 and is disposed within the aperture 156 of the base 152
in the assembled condition. The post 164 may include external
threads to provide at least somewhat of an interlock between the
seat 104 and the base 152. Other ways of interlocking the seat 104
and base 152 (or stated another way maintaining an assembled
condition) could be utilized. In any case, rotation of the post 164
within the aperture 156 thereby allows the seat 104 to rotate or
swivel relative to the base 152. Enhancement of this motion may be
provided by utilizing a plurality of the ball bearings 160 or the
like that engage each of the platform 112 and the base 152, and
that may be disposed in any appropriate arrangement. The ball
bearings 160 need not be disposed equidistantly from the post 164.
Stated another way, the various ball bearings 160 need not be
positioned along a common arc. In the illustrated embodiment, a
pair of ball bearings 160 are spaced inwardly from each of the four
sides of the platform 112 generally at the midpoint thereof.
[0080] The various ball bearings 160 may be captured within an
appropriate recess or the like formed on a lower seat surface 106b
of the seat 104 that projects toward and/or interfaces with the
base 152, more specifically its upper base surface 153a. Preferably
these ball bearings 160 are able to rotate relative to the platform
112 of the seat 104, as well as relative to the base 152. The ball
bearings 160 need not be "contained" in relation to their
engagement with the upper base surface 153a, which is planar in the
illustrated embodiment.
[0081] The ball bearings 160 are also preferably positioned to
enhance the stability of the seat 104 on the base 152. One way to
enhance this stability is to position at least one ball bearing 160
within about 4 inches, and more preferably within about 2 inches,
of each of the four sides of the base 152. Preferably, a plurality
of ball bearings 160 are disposed within the noted distance of the
perimeter of the base 152 (e.g., at least one ball bearing 160
spaced inwardly from each "side" of the base 152). Another way to
enhance the stability of the seat 104 on the base 152 is to
position the center of all ball bearings 160 at least about 2
inches in one embodiment, and at least about 3 inches in another
embodiment, from the center of the post 164. Both of these
stability enhancing features are preferably used.
[0082] The aperture 156 associated with the base 152 may be
threaded. The base 152 may then be threaded onto the threaded post
164 associated with the seat 104. The amount of resistance offered
when rotating the seat 104 relative to the base 152 may be
established by how far the base 152 is threaded onto the post 164.
This in effect determines how "tightly" the ball bearings 160 are
retained between the seat 104 and the base 152. Once the desired
degree of rotational resistance is realized, a nut 165 may be
threaded onto the end of the post 164 to complete the attachment of
the base 152 and seat 104. A lock also may be provided to fix the
position of the seat 104 relative to the base 152 (not shown) to so
as to preclude relative rotation therebetween (e.g., a pin that
would extend within/through the platform 112 of the seat 104 and
the base 152).
[0083] The portable seating device 100 may be used in a "lawn
chair" like application by using the above-noted stand 172. The
stand 172 disposes the base 152 of the portable seating device 100
at a certain position above the relevant supporting surface (e.g.,
the floor, the ground). Reference may be made back to FIGS. 1-2, as
well as FIG. 13 with regard to this particular application. This
stand 172 may be characterized as having a first end 176 that
interfaces with the base 152, as well as a second end 178 that
interfaces with the relevant supporting surface. There are a number
of key features in relation to the stand 172. One is that the stand
172 may be installed on and removed from the base 152 without the
requirement of any tools. In one embodiment this is provided by
utilizing a press fit or snap-lock 192 between the stand 172 and
the base 152. This press fit or snap-lock 192 may provide the sole
source for retaining the stand 172 relative to the base 152.
However, other mechanisms may also be utilized (e.g., brackets).
For instance, a locking pin 194 may be directed through aligned
holes in the base 152 and the stand 172. Another desirable feature
of the stand 172 is that it may be collapsed for enhancing the
transport of the portable seating device 100 after its removal from
the base 152. In any case, preferably the installation of the stand
172 on the base 152, as well as the removal of the stand 172 from
the base 152, does not require any tools, and thereby may be done
solely by hand. Any suitable configuration may be utilized for the
stand 172 that provides the is type of desirable functionality.
[0084] There are two main components of the stand 172 in the
illustrated embodiment, namely a first support 180 and a second
support 182. These supports 180, 182 are pivotally interconnected
by a pair of pivot pins 184. Each of the first and second supports
180, 182 include a pair of laterally spaced first and second legs
186, 188, as well as a pair of vertically spaced cross members 190.
One cross member 190 from each of the legs 186, 188 thereby
collectively define the first end 176 of the stand 172, while the
opposite cross member 190 from each of the legs 186, 188 thereby
collectively define the second end 178 of the stand 172.
[0085] At least one of, and more preferably each of, the first
support 180 and second support 182, are able to extend or retract
to a desired length (i.e., to change the magnitude of the vertical
spacing between the base 152 and the cross member 190 of the
associated first support 180 or the second support 182). The first
support 180 and/or the second support 182, specifically each of
their respective legs 186, 188, may be configured in the manner
illustrated in FIG. 14. Here, an inner tube 183a and an outer tube
187a are telescopingly engageable. The inner tube 183a includes an
end 183b and a compressible/extendable locking pin 185 (e.g.,
spring biased to the extended position). The outer tube 187a
includes an end 187b and plurality of adjustment holes 189. Any
appropriate number of holes 189 may be utilized. The end 183 of the
inner tube 183a is directed into the end 187b of the outer tube
187b, the pin 185 is depressed, and the inner tube 183a is advanced
relative to the outer tube 187a to position the pin 185 associated
with the inner tube 183a in alignment with the desired hole 189 on
the outer tube 187a. Releasing the pin 185 will thereby lock the
position of the inner tube 183a relative to the outer tube 183b.
Changing which hole 189 the pin 185 interfaces with will of course
change the length of the leg 186, 188 that uses the configuration
of FIG. 14. Adjusting the length of one or both of the first
support 180 and second sport 182 may be used to dispose the seat
104 in at least generally a horizontal position, even when the
portable seating device 100 is being used on a sloping surface.
[0086] The portable seating device 100 provides a number of
advantages over existing portable seating devices. One is the
ability to adjust the vertical position of the first backrest 128
relative to the seat 104. Another is the ability to adjust the
position of the second backrest 130 relative to the first backrest
120 to further enhance user comfort. That is, the position of the
second backrest 130 may be adjusted without having to change the
position of the first backrest 128. Including that swivel 154 to
allow the seat 104 to rotate or swivel relative to the stationary
base 152 allows an individual using the portable seating device 100
to turn and yet have the portable seating device 100 provide
support for the individual's back.
[0087] The ability to remove the stand 172 from the base 152 and to
be able to collapse the frame 120 enhances the portability of the
portable seating device 100. In one embodiment, the volume of space
occupied by the base 152, seat 104, and the backrest assembly 127
when the frame 120 is collapsed is relatively compact. Stated
another way and in one embodiment, the portable seating device 100
in the position illustrated in FIG. 9 has a maximum length
dimension (from the rear of the device 100 to its front) of no more
than about 18 inches, a maximum width dimension of no more than
about 18 inches (from one side of the device 100 to its opposite
side), and a maximum height dimension of no more than about 12
inches. Relatedly, the portable seating device 100 is preferably
light in weight. In one embodiment, the portable seating device 100
(without the stand 172) weighs no more than about 10 pounds in one
embodiment, no more than about 7 pounds in another embodiment, and
no more than about 5 pounds in yet another embodiment.
[0088] The portable seating device 100 is also very versatile in
that the portable seating device 100 may be adapted to the needs
for multiple seating applications. As noted above, the portable
seating device 100 may be configured for a lawn chair-like
application when the stand 172 is attached to the base 152.
However, the portable seating device 100 also may be used without
the stand 172. In this case the base 152 is disposed directly on an
appropriate supporting surface, such as a bleacher, the ground, or
the like. Certain features are incorporated into the design of the
portable seating device 100 to accommodate this case where the
stand 172 is not utilized, namely in relation to the stability of
what may be characterized as a reconfigured portable seating device
100. One way to realize a desired degree of stability is for the
seat 104 and base 152 to be at least generally of the same size
(e.g., in relation to their respective outer perimeters). Another
is the above-noted positioning of the bearings 160 relative to the
axial post 164, both of which collectively define the swivel 154
between the seat 104 and the base 152. Moreover, preferably the
upper base surface 153a is disposed no more than about 2.5 inches
from the supporting surface when the base 142 is disposed directly
on an appropriate supporting surface without the stand 172. In one
embodiment, a lower seat surface 106b of the seat 104 and an upper
base surface 153a of the base 152 are separated by a space of no
more than about 1/4 inch. This thereby defines what may be
characterized as a low profile for enhancing stability of the
portable seating device 100.
[0089] The lower base surface 153b of the base 152 is also
preferably configured such that it will not "rock" when disposed on
a flat supporting surface, regardless of where the load is applied
on the base 152. Stated another way, the lower base surface 153b is
preferably configured such that the base 152 may be supported on a
flat supporting surface so that the base 152 has a constant
vertical position relative to this supporting surface. In any case,
this may be provided by having the lower base surface 153b be at
least generally planar (not shown), by having multiple low profile
rails, feet, legs, or the like on this lower base surface 153b, or
by having the lowest portions of the lower base surface 153b be
disposed within a common reference plane and oriented to provided
the desired stability. In this regard and for the case of the
illustrated embodiment, the base 152 includes a rim 150 that is
disposed about the perimeter of the base 152. The rim 150 defines
the lowest extreme of the lower base surface 153b, and further is
disposed in a common reference plane. The press-fit joint 192 does
not extend beyond the distal end of the rim 150. The remainder of
the lower base surface 153b could include a grid of ribs or the
like that terminated at the same elevation as the lowest extreme of
the rim 150 (not shown). In one embodiment, those portions of the
base 152 that interface with the supporting surface when the base
152 is disposed directly thereon collectively define a perimeter
having an area of at least about 144 in..sup.2, and at least about
289 in..sup.2 in another embodiment. Stated another way, the
perimeter of the base 152 encompasses/defines an area of at least
about 144 in.sup.2. Preferably the center of this "support" region
or area coincides with the center of the area defined by the
perimeter of the seat 104.
[0090] The portable seating device 100 may include an appropriate
structure for at least somewhat securing the base 152 to an
appropriate support on which it may be disposed (e.g., a bleacher;
a seat of a picnic table) with the stand 172 having been removed
therefrom. One such structure is illustrated in FIGS. 15A-C. FIG.
15A illustrates a front face 152a of the base 152. Holes 300a-d
extend at least within the base 152. In the illustrated embodiment
and referring to FIG. 15B, the holes 300a-d extend through the rim
150 associated with the base 152 in the illustrated embodiment. In
any case, one hook or clamp 304a interfaces with the holes 300a,
300b, while another hook or clamp 304b interfaces with the holes
300c, 300d. An appropriate biasing member 314a, 314b is associated
with the corresponding clamp 304a, 304b (e.g., a coil spring).
[0091] Each clamp 304a, 304b includes a first section 306, a second
section 308, a third section 310, and a stop 312. The first section
306 of the clamp 304a is disposed within hole 300b, the second
section 308 of clamp 304a extends between the holes 300a, 300b on
the exterior of the base 152, and the third section 310 of clamp
304a extends back within the hole 300a. The biasing member 314a is
disposed between the stop 312 of the clamp 304a and the rim 150,
and biases the clamp 314a into the stowed position of FIG. 15B.
Similarly, the first section 306 of the clamp 304b is disposed
within hole 300c, the second section 308 of clamp 304b extends
between the holes 300c, 300d on the exterior of the base 152, and
the third section 310 of clamp 304b extends back within the hole
300d. The biasing member 314b is disposed between the stop 312 of
the clamp 304b and the rim 150, and biases the clamp 304b into the
stowed position of FIG. 15B.
[0092] FIG. 15B illustrates the stowed position for the clamps
304a, 304b. In order to secure the base 152 to a bleacher or the
like using the clamps 304a, 304b, the user simple pulls the clamps
304a, 304b out and away from the front face 152a of the base 152 so
that the third section 310 of each clamp 304a, 304b is now disposed
beyond the front face 152a of the base 152. This is done by
compressing the biasing member 314a between the rim 150 and the
stop 312 of the clamp 304a, and by compressing the biasing member
314b between the rim 150 and the stop 312 of the clamp 304b in the
illustrated embodiment. The clamps 304a, 304b may then be rotated
within their corresponding hole 300b, 300c to dispose the second
section 308 of each clamp 304a, 304b in an at least generally
vertical position. This then disposes the third section 310 in at
least somewhat of a horizontal position, under the front portion of
the base 152, and as illustrated in FIG. 15C. A bleacher or the
like may then be disposed between the third section 310 of each
clamp 304a, 304b and the bottom of the base 152. It should be
appreciated that the clamps 304a, 304b could be disposed in the
deployed position of FIG. 15C while the portable seating device
100, without the stand 172, already being positioned on the
relevant surface.
[0093] There are yet other options for reconfiguring the portable
seating device 100. The upper tube 122 of the frame 120 and the
backrest assembly 127 may be removed from the remainder of the
portable seating device 100 and used all by itself as a support for
an individual's back. One example of this application is
illustrated in FIG. 16. Here, a "chair" 196 has some type of back
198 and a seat 200. The backrest assembly 127 may be mounted on
this back 198 in any appropriate manner, such as by using a strap
202. The upper tube 122 of the frame 120 and the backrest assembly
127 may be disposed between the user's back and any appropriate
support.
[0094] Another embodiment of a portable seating device is
illustrated in FIGS. 17A-D and is a variation of the illustrated
version of the portable seating device 100 discussed above, and
therefore is identified by reference numeral 100'. Corresponding
component illustrations of these two embodiments are identified by
the same reference numeral. Those corresponding component
illustrations that differ in at least some respect are further
identified by a "single prime" designation. Only the seat 104' (the
cushion or upper section 108', together with the platform or lower
seat section 112') and the base 152 are illustrated in FIGS. 17A-B.
However, the portable seating device 100' preferably includes each
of the above-described features of the portable seating device 100.
For instance, the portable seating device 100' may include the
detachable stand 172, the backrest assembly 127, and the frame 120
that interconnects the backrest assembly 127 with the seat 104', as
well as all of the variations addressed herein.
[0095] FIGS. 17A-B schematically illustrate a bearing assembly or
swivel 234 that rotatably interconnects the seat 104' with the base
152. Any appropriate way of allowing the seat 104' to rotate or
turn relative to the base 152 may be utilized by the portable
seating device 100'. Moreover and with the stand 172 having been
detached from the base 152, instead of using the arrangement of
FIGS. 15A-C to detachably mount the base 152 on an appropriate
supporting structure (e.g., a bench), the portable seating device
100' uses one or more Velcro.RTM. straps 236 (only one illustrated
in FIG. 17A). Any appropriate way of detachably interconnecting the
base 152 with an appropriate supporting structure with the portable
seating device 100' being in the noted configuration (without the
stand 172) may be utilized, including the arrangement of FIGS.
15A-C.
[0096] The portable seating device 100' of FIGS. 17A-D illustrates
one or more storage compartments for its seat 104'. In this regard,
the upper seat section 108' is movable at least generally away from
the platform 112' to access one or more internal storage
compartments of the seat 104'. As illustrated, the upper seat
section 108' is movably interconnected with the platform 112' by a
hinge 220 of any appropriate size, shape, configuration, and/or
type so as to pivotally interconnect a rear portion of the upper
seat section 108' with a rear portion of the platform 112'. Other
types of movable interconnections may be appropriate. It may be
such that the upper seat section 108' could be detachably
interconnected with the platform 112' so as to be totally removable
from the platform 112' to access one or more internal storage
compartments for the seat 104'.
[0097] Pivoting the upper seat section 108' at least generally away
from the platform 112' in the illustrated embodiment of the
portable seating device 100' (FIG. 17B configuration) provides
access to one or more internal storage compartments of the seat
104'. In the illustrated embodiment, the upper seat section 108' is
in the form of: 1) an upper section (e.g., a compressible material,
such as foam or the like) that interfaces with a user of the
portable seating device 100'; and 2) a lower section (e.g., that
provides structural support for the upper section and that provides
for a desired interconnection with the platform 112'). In any case,
FIG. 17C illustrates a plan view of the lower surface of the upper
seat section 108' (the above-noted lower section), or that surface
of the upper seat section 108' that faces or projects toward the
platform 112' when the upper seat section 108' is disposed over/on
the platform 112' (the FIG. 17A configuration). The underside of
the upper seat section 108' may be a hollow structure. As such, the
seat 108 may include one or more reinforcement ribs 222. Any
appropriate number of reinforcement ribs 222 may be utilized.
Moreover, these reinforcement ribs 222 may be of any appropriate
size, shape, and/or configuration, and may be disposed in any
appropriate arrangement. If the above-noted lower section of the
upper seat section 108' was in the form of a solid structure, the
reinforcement ribs 222 may not be required.
[0098] The lower surface of the upper seat section 108' also
includes one or more storage compartments 224. Any appropriate
number of storage compartments 224 may be utilized. Moreover, the
storage compartments 224 may be of any appropriate size, shape,
and/or configuration, and may be disposed in any appropriate
arrangement (e.g., a given storage compartment 224 may be disposed
at any appropriate location on the lower surface of the upper seat
section 108').
[0099] The perimeter of each storage compartment 224 of the upper
seat section 108' is defined by one or more partitions 226. One or
more of the reinforcement ribs 222 may also function as a partition
226 (those identified by a "226/222" designation). One or more of
the partitions 226 may be maintained in a fixed position relative
to the upper seat section 108' (those partitions 226 that are
identified by a solid line), one or more of the partitions 226 may
be detachably interconnected with the upper seat section 108' in
any appropriate manner (e.g., a "snap-lock") so as to be movable to
a new position and then re-engaged (via a detachable
interconnection) with the upper seat section 108' so as to change
the size, shape, and/or configuration of the corresponding storage
compartment(s) 224 (those partitions 226 that are identified by a
dashed line), or both. That is, the perimeter of a given storage
compartment 224 may be entirely defined by fixed partitions 226,
may be entirely defined by detachable partitions 226, or may be
defined by a combination of one or more fixed partitions 226 and
one or more detachable partitions 226.
[0100] FIG. 17D illustrates a plan view of the upper surface of the
platform 112', or that surface of the platform 112' that faces or
projects toward the upper seat section 108' when the upper seat
section 108' is disposed over/on the platform 112' (the FIG. 17A
configuration). The platform 112' may be a hollow structure with
one or more reinforcement ribs 228. Any appropriate number of
reinforcement ribs 228 may be utilized. Moreover, these
reinforcement ribs 228 may be of any appropriate size, shape,
and/or configuration, and may be disposed in any appropriate
arrangement. If the platform 112' was in the form of a solid
structure, the reinforcement ribs 228 may not be required.
[0101] The upper surface of the platform 112' also includes one or
more storage compartments 230. Any appropriate number of storage
compartments 230 may be utilized. Moreover, the storage
compartments 230 may be of any appropriate size, shape, and/or
configuration, and may be disposed in any appropriate arrangement
(e.g., a given storage compartment 230 may be disposed at any
appropriate location on the upper surface of the platform
112').
[0102] The perimeter of each storage compartment 230 is defined by
one or more partitions 232. One or more of the reinforcement ribs
228 may also function as a partition 232 (those identified by a
"232/228" designation). One or more of the partitions 232 may be
maintained in a fixed position relative to the platform 112' (those
partitions 232 that are identified by a solid line), one or more of
the partitions 232 may be detachably interconnected with the
platform 112' in any appropriate manner (e.g., a "snap-lock") so as
to be movable to a new position and then re-engaged (via a
detachable interconnection) with the platform 112' so as to change
the size, shape, and/or configuration of the corresponding storage
compartment(s) 230 (those partitions 232 that are identified by a
dashed line), or both. That is, the perimeter of a given storage
compartment 230 may be entirely defined by fixed partitions 232,
may be entirely defined by detachable partitions 232, or may be
defined by a combination of one or more fixed partitions 232 and
one or more detachable partitions 232.
[0103] Each storage compartment 224 of the upper seat section 108'
is aligned with a particular storage compartment 230 of the
platform 112' when the upper seat section 108' is disposed over/on
the platform 112' (the FIG. 17A configuration). Each storage
compartment 224/storage compartment 230 pair thereby collectively
define a larger storage volume or space. Other configurations may
be appropriate. For instance, it may be such that the storage
compartments 224 of the upper seat section 108' are of a sufficient
depth so as to not require alignment with a storage compartment 230
of the platform 112' to provide a suitable storage volume or space.
In this case, it may be desirable to provide a detachable cover for
each storage compartment 224 of the upper seat section 108' (not
shown). Each storage compartment 224 of the upper seat section 108'
could have its own cover, or a cover could enclose two or more
storage compartments 224 (including all storage compartments 224).
Similarly, it may be such that the storage compartments 230 of the
platform 112' are of a sufficient depth so as to not require
alignment with a storage compartment 224 of the upper seat section
108' to provide a suitable storage volume or space. In this case,
it may be desirable to provide a detachable cover for each storage
compartment 230 of the platform 112' (not shown). Each storage
compartment 230 of the platform 112' could have its own cover, or a
cover could enclose two or more storage compartments 230 (including
all storage compartments 230).
[0104] In summary, the seat 104' may include one or more "internal"
storage compartments. One or more storage compartments 224 may be
integrated with the upper seat section 108' and without having any
storage compartment for the platform 112 (not shown). One or more
storage compartments 230 may be integrated with the platform 112'
and without having any storage compartment for the upper seat
section 108' (not shown). One or more storage compartments 224 may
be integrated with the upper seat section 108' in combination with
having one or more storage compartments 230 integrated with the
platform 112'. Each storage compartment 224 of the upper seat
section 108' may cooperate with a corresponding compartment 230 of
the platform 112' to collectively define a larger storage volume or
space. Finally, each storage compartment 224 of the upper seat
section 108' and each storage compartment 230 of the platform 112'
may define an autonomous storage volume or space (not shown).
